CONICAL HONEYCOMB BODY HAVING CHANNELS EXTENDING RADIALLY OUTWARD AT AN ANGLE AND HONEYCOMB BODY ASSEMBLY

摘要

A honeycomb body includes wound and/or stacked layers having a geometric center axis, a cavity rotationally symmetrically around the center axis and an outer lateral surface. Each layer extends approximately concentrically around the axis. At least one of the layers is at least partially structured forming channels through which a fluid can flow. The channels extend from the cavity outward to the outer lateral surface at a non-right cone angle to the axis. The channels have a cross-section changing along the channels from inside to outside. At least one structured layer and at least one intermediate layer are alternatingly disposed and helically layered. The structure height of the structured sheet-metal layer forming the channels is substantially constant and channel cross-sectional areas increase from inside to outside. The intermediate layer can be made of simple wires or of specially cut or folded smooth sheet-metal layers.

1. A honeycomb body, comprising:
an inside, an outside and a geometric central axis; wound or stacked layers each running concentrically around said central axis and defining an outer lateral surface and a cavity disposed rotationally symmetrically around said central axis; at least one of said layers being at least partially structured to form a multiplicity of channels through which a fluid can flow; said channels running outwardly from said cavity to said outer lateral surface at a non-perpendicular cone angle relative to said central axis; said channels having a channel cross section varying over a course of said channels from said inside to said outside; at least one intermediate layer being disposed in alternation with said at least one structured layer; and said at least one intermediate layer and said at least one structured layer being layered on top of one other in a helical manner.
